People in different countries in the world eat different kinds of things. And people in different countries don’t always eat three times a day. In some place people eat once or twice a day; in other countries, people eat three or four times a day. Scientists say that these differences are not important. It doesn’t matter if a person eats dinner at 4 o’clock in the afternoon or at 11 o’clock at night. The important thing is that every day a person must eat something from each of the seven kinds of food. The most important thing is that we must find some way to help the hungry people and make the people have right kinds of food, make them strong and healthy. Which sentence is right
